Canva AI Generative Fill
Need AI generative fill on a still — paint any region, describe what should appear, and let the model invent pixels that blend with the rest of the photo? CanvaPro’s free Canva AI Generative Fill (also called Canva AI Replacer) is a brush-plus-prompt editor for objects, patches of sky, accessories, and textures — no signup, and no watermark on the download.
What Is AI Generative Fill?
Generative fill is inpainting with a brief. You mark the pixels that are allowed to change, then write what those pixels should become. Unlike a whole-image restyle, the unpainted parts of the photo stay yours: the room, the face outside the mask, the table edge. That makes it a practical AI replacer for local edits — add a flower where a gap is, change sunglasses, extend a bit of wall, or restyle a small surface — without regenerating the entire frame.
Who Uses Canva AI Generative Fill?
- Retouchers filling gaps, replacing a logo patch, or testing an accessory on a portrait they have rights to edit
- Designers mocking a poster on a wall or a label on a bottle inside a real photo
- Listing teams swapping a small SKU detail without a full reshoot
- Hobby editors trying creative fills — a different sky patch, a new mug, a daisy in a vase
How Canva AI Generative Fill Works
Upload a JPG, PNG, or WEBP (up to 5 MB). Draw a mask with the brush; trim with the eraser; undo if you overpaint. Describe the fill in the prompt field, complete the security check, and click Generate. The result lands back on the canvas so you can keep the same mask and try a new sentence, or mask a second region and continue.
Precision Masking
The mask is the contract. If you paint too little, leftover original pixels fight the new fill. If you paint far beyond the subject, nearby furniture may morph. Stay close to the feature you want changed. Use a smaller brush on glasses arms, jewelry, and label corners. Toggle brush-mark visibility before you submit so you are not guessing at coverage.
Prompts That Blend
Write the object or material as it should exist in this photo, not as a separate stock cutout. “White daisy in the same vase, matching window light” beats “flower.” “Clear aviator sunglasses with thin metal frames” beats “cool glasses.” Mention finish (matte, glossy, worn leather) when that is the point of the edit. If a generate ignores lighting, add one lighting clause and try again rather than stacking ten adjectives.
Fill Anything vs. Whole-Scene Restyle
Generative fill is a scalpel. It is the right tool when 90% of the picture is already correct. If you wanted a brand-new illustration of the entire scene, a full generator would be a different job. Here the value is surgical: one accessory, one wall patch, one product face, one bit of missing texture — described in plain language and bounded by your brush.
Tips for Natural Generative Fill
Start from a sharp original. Match prompt scale to mask size (a “city skyline” inside a tiny rectangle will look toy-like). After a good fill, download immediately. Keep the untreated file so you can branch another idea without compounding compression. If the fill seams, expand the mask by a few pixels so the blend has a transition zone.
Privacy & Security
Uploads travel over HTTPS. We do not sell your edits or portraits. Files are processed to complete the generate. You stay in control from upload to download.
